APPLICATION FILED MMI. I5. |918.

Patented Nov. 4, i919.

A TTORE Y projecting ribs or rails 13V formed longitudinally along theirl inner edges, which are so arranged that, when the blocks are properly assembled in a wall in combination with the blocks 2, the ribs 13 will project within Ythe channels of adjacent tie blocks 2 and the latterblocks .serve to hold the face blocks together in proper relation.

On-the inner faces of the'blocks 3, I also s provide horizontally extending, dove-tailed placed, end to end, in proper alinement on a foundation, mortar' being applied` between the joints and then on the upper faces. The face blocks are. then arranged as is particularly shown in Figs. II andv III, the inner walls ofthe blocks being placed back, to backy so that thejlower ribs 13 of the blocks Vse'atwithinthe rupper facel channels of the.l

lower tie course. Mortar' is also filled in between the `blocks and within the dove- -tailed keyways and between the ends of ad jacent blocks to form a perfectly tight joint between all of thel lOlQcks. rlhiese face blocks are also placed to bring the joints in oli'- setl relation as is s hown'in Fig. III so that at no place inthe wall is there a direct joint through the wall.

While itV is not. necessary in ordinary straight walls, if it is desired reinforcing rods 18 may be placedmwithin the upper channels of theblocks of the tie course to strengthen the structure; the tie blocks being provided with centrally located longitudinally extending grooves 1,9 wherein the rods may seat. t f

I have also provided a sort of `S-shapedl connecting clip 20 (Fig. IX) which may be used to j further tie the face blocks together-S; these ties being inserted in the mortar keyways formed.- within the adjacent` dovetailed grooves, as shown in Fig, I.

YAnother tie course is then placed to cover i the upperfaces of the course of face blocks and this ties them securely together, the wall being completed by alternately laying courses yof tie and face blocks.

In Fig`- VI., I have shown a form of tie block wherein the upper face wall is slotted longitudinally so that a reinforcing rod22 may be placedz therein and the space thereaboutlled with mortar to embed therod. This construction permits the use of more or heavier reinforcing and `enables the wall to be strengthened lsuiiiciently to withstand a maximum amount o f pressure.

ing of the blocks together, whileFig. VII

shows a plane surfaced block.

` It is apparent that a wall constructed of blocks so formed and assembled .will form a structure wherein there are no direct joints vthrough the wall, all the blocks being 70 interlocked together to give-the structure rigidityl and strength andA making it absolutely air, water and .-verminproof.V While I have shown the wall constructed of hollow tile, I do' not'wish tov be limited to this .particular type of block, asit is apparent that solid blocks could-be used with'v like results. v Y 'i Itis further apparent Vthat the air spaces in the 'blocks prevent external Vtemperatures Y from affecting the internal face ofthe wallS.

so that sweating ofthe blocks is prevented.

Having thus described my'invention, what I claim to be new therein and desire to secure by Letters-Patent, is

l. Agwall construction consisting of two sets of tiles superposed one upon the other in alternate rows, those ofone set each having a horizontal web portion with vertical side 'flanges above and below the web, those 90 of the other set consisting of block members f having separate halves arranged back -to back, said block members having `upper rand i lowerjtongues intermediate the side faces thereof, the tongues tting into the space between the flanges of the other set, longitudinal alining grooves Vin the adj acent back faces of the opposite halves of the respective blocks,'and S-,shaped key members en- Y gaging the grooves to secure the two halves together. j f y 2.V A wall construction consisting of vtwo sets of tiles superposed oneupon the other in alternate rows, those of oneset each hav- Ving a horizontal web Vportion with vertical side flanges above and below vthe web, those,

of the other set consisting of block members having separate halves arranged backV to back, said'block members having upper and lower tongues intermediate the side faces 110 thereof, the tongues fitting' into thespace between the flanges of the Vother set, longitudinal alining'dove-tailed groovesin the adjacent back faces of the opposite halves of the respective blocks, S-shaped keyjmem- 11,5 bers engaging the under-cutportions ofthe dove-tailed grooves, and cementitious material in the dove-tailed grooves in which the S-shaped key members. are embedded.
